Characterization of Aluminum Surfaces Prepared for Adhesive Bonding.

Abstract

Scanning transmission electron microscopy (STEM), AES, and ESCA have been used to characterize changes that occur with handling and hydration on aluminum surfaces prepared for adhesive bonding. Three commercial surface treatments were considered - FPL, PAA, and CAA. The resulting surfaces are amorphous aluminum boemite when subjected to a humid, elevated temperature environment. It was also found that PAA surfaces are highly resistant to mechanical damage, but quite susceptible to grease contamination. (Author-PL).
